| Abstract | The nuclear orphan receptor COUP-TFII is a transcription factor of the steroid/thyroid hormone receptor superfamily. It is primarily expressed in mesenchymal tissues during embryogenesis and is required for normal cardiovascular development. Loss of the COUP-TFII gene in mice results in embryonic lethality due to a variety of cardiovascular abnormalities, including defects in angiogenesis and heart development. To further dene the role of COUP-TFII during cardiovascular development, we have analyzed the cell-specic expression pattern of COUP-TFII within the forming vasculature using gene knock-in, in situ hybridization, and immunohistochemistry techniques. Here we demonstrate in mouse embryos that COUP-TFII is differentially expressed between arteries and veins, suggesting a role for COUP-TFII in arteriovenous differentiation. Furthermore, we show the formation of embryonic arteriovenous malformations in the absence of COUP-TFII, a hallmark of defective arteriovenous differentiation. |
